The operation of the clutch operating mech- 55 The frame H! has a pair of vertical walls lila anism will now be described. As the shaft I2 55 is rotated, the disk 20 rotates therewith. Beginning with the parts as shown in Figs. 1 and 2, the rollers are substantially at the outer periphery of the disk, and the clutch part I4 is at its extreme left position looking at Fig. 1. To move the clutch part I4 to the right for engagement with another clutch part of any suitable kind, not shown, the hand lever 34 is moved in a clockwise direction from the position shown in Fig. 2 to the position shown in Fig. 3. During such operation the arm 31 is likewise turned in a clockwise direction to pull the rod 38 downwardly andv swing the upper ends of the members 4!] inwardly. Such movement causes the rollers-46 to press against the outer conical surface of the clutch part I4 for moving the latter to the. right longitudinally of the shaft I 2, and causing engagement thereof with the other clutch part, not' shown in the drawings. During this movement the arms 50 being fixed to shafts 3|, swing with thelevers 40.

Torelease'the clutchpart l4, the handle 34 is swung in the opposite direction, moving the arms of the members 40 outwardly and causing arms to swing out and the rollers 52' to press against the inner surface of disk 20 to.

move the clutch M to the left for disengaging the same. The arms 50 thus follow the movement of the, arms 45, the rollers 5| remaining in engagement with the inner conical surface 2! of the clutch disk- 20 during movement of the clutch part to the left or right.

It will be understood that the hand lever 34 may be replaced by a foot pedal arrangement or other power device for actuating the mechanism l5.

In Fig. '7 there is shown a modified constructionin which the members 41 are omitted. The rollers 46 press against the outer conical surface of the disk 20 for'moving the clutch part H3 in one. direction. To move the said clutch part in the opposite direction, there is provided a coil compression spring disposed about the hub portion l6" for maintaining the disk 20 in contact with the rollers 46.

It will thus be seen that there is provided a" device inwhich the several objectsof this invention are achieved, and which is well adapted. to meet the conditions'of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodimentsabove set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is' to be interpreted as illustrative and not in a limiting sense.
